Abstract (en)
[origin: US6654596B1] A homodyne radio receiver apparatus receives radio frequency signal bursts containing a number of symbols and generates digital samples of at least a complex base band signal (I and Q) of each signal burst. A DC compensator comprises an average calculator (8,8'), which determines an average DC-level of said samples, and a signed square sum calculator (9,9'), which calculates a signed square sum of a plurality of said samples and weights the square sum by a compensation factor. Correction means (10,10') subtracts the square sum from an output of said average calculator means for forming the DC-level estimate.
